Daily Deal: Free Mini-Burger at Pattywagon

It's not a huge deal, but it's something. The Patty Wagon food truck (@pattywagonla) is celebrating the official start of summer by giving a free classic mini-cheeseburger to the first 25 people who show up at each stop (they have two trucks, and each makes a stop for lunch and a stop for dinner) and show that they have posted on Twitter or Facebook "I'm celebrating the first day of summer by eating a Patty Wagon burger!" with the purchase of another mini burger or a side of fries.
